Use the information to complete problems 9 and 10. The table below lists the first name and date of birth for five students. The information is presented in letters (for the names) and digits (for the birth dates). The total characters for any given student is made up of both letters and digits in their data. The characters of the names are not case sensitive. For example, Trent's characters are t, r, e, n, t, 8, 1, 2, 9, and 7. Trent Ramiro Mara Pam Fina 8-12-97 6-15-98 10-9-98 2-12-98 7-15-97 9. If a student is chosen at random from the group, what is the probability that the choice will contain a repeated letter or a repeated digit?
